Description

In DSE versions 5.1.2 and earlier, sets the field name in the input file that will define
the outgoing vertex of an edge. Both outV and inV must be defined in an edge mapping statement. In DSE 5.1.3
and later, the field_name is deleted from between the outV keyword
and the {.

Examples

DSE 5.1.2 and earlier: Set the field name for the outgoing vertex of an edge in a mapping
script to
ingredient.

//Sample line read:
// city_id|sensor_id|name
// santaCruz|93c4ec9b-68ff-455e-8668-1056ebc3689f|asparagus
// The outgoing vertex has a vertex label of ingredient, the particular vertex is defined as the one with
// the name of asparagus
outV "ingredient", {
label "ingredient"
key "name"
}

The
field name in the input file that defines the outgoing vertex is ingredient, the
vertex has a vertex label of ingredient, and the key value name is supplied in
the input file field set in this statement. The label and
key must be set along with outV.
